What is the difference between TRX and TRON?

Could you please elaborate on the distinction between TRX and TRON? I've heard of both terms but am a bit confused about their specific roles and functions within the cryptocurrency ecosystem. I'm particularly interested in understanding how they differ from each other and what advantages or disadvantages might exist for investors considering either option. Could you also provide some insight into the practical applications of TRX and TRON in the broader context of finance and blockchain technology? Thank you for your assistance in clarifying this matter.
